🔍 Key Concepts

• Cold weather effects on batteries and electrical equipment • Mechanical reliability of air start and hydraulic systems in low temperatures • How temperature affects pressure vs electrical capacity

💭 Think About

• Think about which system depends most on chemical reactions that slow down significantly in cold temperatures. • Consider which systems mainly move fluids or compressed air and how much they are affected by low temperatures compared to systems that depend on stored electrical energy. • Ask yourself: Which system is most likely to have reduced power output or failure to deliver enough starting torque when it is very cold?

✅ Before You Answer

• Identify which option relies heavily on battery performance. • Consider which systems can still operate effectively as long as pressure is maintained in an accumulator or air bottle. • Before choosing, eliminate the options that mainly involve compressed air or hydraulic pressure, which are generally more tolerant of cold than batteries.
